JNCIA-DevOps Python And PyEZ Practice Question
You are writing a script that uses Jinja2 to dynamically render a Junos interface configuration. Which Python module and function are required to load a template from the local filesystem and render it with a dictionary of variables?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
from jinja2 import Environment, FileSystemLoader
Jinja2 utilizes a FileSystemLoader to find templates on disk and an Environment to manage them, allowing you to get_template() and render() with context variables.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
from jnpr.junos.cfg import ConfigTemplate
Why it's wrong here
ConfigTemplate does not exist in this namespace for rendering external Jinja2 files.
- ✓
from jinja2 import Environment, FileSystemLoader
Why this is correct
FileSystemLoader and Environment are the standard classes used to load and render templates from files.
- ✗
from jnpr.junos.template import TemplateRenderer
Why it's wrong here
This is a distractor module path; standard Jinja2 classes are used directly in PyEZ workflows.
- ✗
import jnpr.junos.utils.jinja as jinja
Why it's wrong here
PyEZ relies on the native Jinja2 library rather than a proprietary wrapper for rendering.
